METAL FEED-THOUGH.

Application filed Deeember'27, 1919.

T 0 all whommay concern:

Be it known that I, NATHAN ALLEN GIB- BONS, a citizen of the United States of Amen ica, and resident of Martins Ferry, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Metal Feed-Troughs, of which the following is a specification.

This invention relates broadly to feed troughs, and more particularly to a trough composed wholly of sheet metal.

The primary object of the invention is to provide a simple, strong, durable and comparatively inexpensive sheet metal trough embodying supports composed of the same material.

A. further object is to provide a trough having a structure adapting it for shipment in knock-down form nested with other similar troughs and which may be readily set up by any ordinary unskilled person with out the employment of special tools.

IVith these and other objects in view, the invention resides in the features of construction, arrangement of parts and. combinations of elements which willhereinafter be fully described, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of the invention;

Fig. 2 is a partial perspective view of one end of the trough body with its support removed;

Fig. 8 is a perspective view of a support,

' detached Fig. 4 is an enlarged vertical section of an end of the invention;

Fig. 5 is an end elevation, showing another form of support;

Fig. 6 is a central section of the support shown in Fig. 5;

Fig. 7 is an end elevation, partly in broken section, illustrating still another form of support;

Fig. 8 is a central vertical section of the support shown in Fig. 7 and- Fig. 9 is an enlarged horizontal section taken on line 9-9, Fig. 2.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views A indicates generally the body portion, and B the opposite ends of a trough. formed of a single metal sheet. Said body portion has downwardly and inwardly inclined sides Specification of Letters Patent.

1 and a curved bottom 2; and each of said ends B, shaped to correspond with said body portion A,'1 resentsa plain interior and a folded exterior, the surplus metal developed in turning up said end in closing relation to the body being utilized to form two opposimilar size and form and have their con-- frontlng edges inclined convergently in upward and inward directions.

The opposite ends B of the trough are mounted upon detachable supports 0 each of which is composed of a single piece of sheet metal shaped to form a substantially upright flat panel 5, a pair of similar forwardly directed side members 6 and a horizontal foot member 7. Said support C is made of greater height than the trough and is designed to have the foot member 7 rest upon the ground or upon a' floor while its upper edge is received under or within a roll or head 8 formed at the upper edge of the flat member 4 of the end B. A portion of the upper edge of each side member 6 is adapted to be received within the roll or head 9 formed atthe upper edge of the ad jacent side 1. of the body portion A of the trough, while an elongated member or tongue 10 formed on the upper portion of each side member is designed to be projected through a slit 11 provided therefor in the head 9, after which said tongue is bentinto overlying clampingrelation to said head.

Carried by the panel 5, as shown in Figs. 1, 3 and i, are two similar tongues 12 de signed to engage with the opposite folds 3 of the adjacent end B for securing the support C in rigid relation to said end of the trough. I Saidtongues are struck up from the metal of said panel at appropriate points and overlie the inner face of said panel in relatively spaced relation and have inclinations corresponding to those of the confronting edges of the folds 8. In applying the support C, the latter is elevated with respect to the end B so as to enter the tongues 12 in the open'spaces 13 behind the folds 3, and is then forced upward until the edges of said folds seat firmly behind said tongues, as indicated in Fig. 1.

In the form of support shown in Figs. 5 and 6, a single centrally located tongue 14 and then forcing the circumscribed area inward to a position inclined somewhat from the plane of the panel. As is obvious, in applying the support C the upper cor- 'ner portions of the tongue 14; enter the open spaces 13 behind the folds 3.

In the form of support shown in Figs. 7 and 8, a single centrally disposed struck-up tongue 15 of isosceles trapezoid form is employed, said tongue being formed by cutting three connected slits having the relation of base and legs of such trapezoid and then turning the metal thus circumscribed inward and thence upward approximately parallel to the plane of the panel. The acute angled wings of said tongue enter the open spaces 13 behind the folds 3 for holding the panel in rigid relation to the end B of the trough.

What is claimed is- 1. A sheet metal trough structure comprising a trough body having integral ends formed with external open folds presenting upwardly and convergently inclined confronting edges, said body and said ends having upper edge beads formed thereon, and supports detachably connected to said ends, each support consisting of a substantially upright panel having its upper edge engaged with the bead of the adjacent end,

inwardly directed side members engaged with the beads of said body, and a tongue carried by said panel disposed in interlocked relation to the opposite folds of the adjacent end of the trough.

2. A sheet metal trough structure comprising a trough body having integral ends formed with external open folds presenting upwardly and convergently inclined confronting edges, said body and said ends having upper edge beads formed thereon and the beads of said body having longitudinal slits formed therein adjacent to their ends, and supports detachably connected to the ends of the trough, each support being composed of a single piece of sheet metal shaped to form a substantially upright panel, forwardly directed side members disposed laterally of said panel and having upright tongues formed at their upper edges, and an inwardly pressed tongue struck up from said panel, said support being adapted for mounting adjacent to an end of the trough with its upper edge underlying the bead of said end, with the struck-up tongue thereof interengaged with said open folds of said end, and with the tongues of said side members received in the slits of said body beads and turned into overlying clamping relation to the latter.

In testimony whereof, I afiix my signature in presence of two subscribing witnesses.
